Recently after tackling a tough virus I discovered along the way that Kaspersky Anti-Virus Program installed ADS code on my entire hard drive. Hijackthis ADS Spy was able to detect and remove all the coded ADS files. ADS means Alternative Data and I did not feel comfortable using Kaspersky again after I found out about this. Needless to say I uninstalled it. a DOS stan along program called LADS also helped in discovering such Code. From what I understand the reasoning behind this code was to supposedly speed up the scanning engine for the program, but I don't know as if I buy that or not to be true. Anyways if anyone else is aware of this please post some feedback.
